Depend on the physique.
Look at Dorians early years, his waist fit his physique, he had that powerful herculean Physique.
Just like Ronnie, in his early years, his tight waist fit perfectly with his sweeping muscle bellies, and frame.
I think the waist proportions are just like anything else, either it fits the physique or it doesnt.
Too small fucks it up, Buchanans waist IMHO was way to small, made him look weak and frail.
Too big fucks it up too. Late Kovacs.
Its funny to me how many people get caught up in the whole black and white thinking. Very small minded. Someone can have a wider waist if it fits the physique, the herculean type. Dorian would look really odd with a very small waist I think.
I cant really think of a term to classify the Flex Wheeler/Ronnie Coleman type physique. Athletic doesnt seem to fit well, neither does artistic. Any thoughts people?
